MANGLE.

Application filed June 23, 1893 Serial No. 78,597. (No model.)

To all whom it may concern.-

Beit known that I, J AMES G. CRAWFORD, of Boston, in the county ofSuifolk and State of Massachusetts,have invented certain new and usefulImprovements in Mangles, of which the following is a specification.

The object of this invention is to provide an improvement in mangles,which will enable a piece of cloth to be more effectively ironed thanheretofore.

To this end, the invention consists in the novel features ofconstruction and combinations of parts described hereinafter and pointedout in the claims.

Referring to the accompanying drawings, which illustrate the invention:Figure 1 shows a side elevation of the machine. Fig. 2 shows alongitudinal section.

The same letters of reference indicate the same parts in both thefigures.

In the drawings: The letter (L designates the supporting-frame of themachine which has hearings on its upper side for two cylinders b and(2', around which the cloth is carried. Each of these cylinders isformed of spiders c, and slats c, which have spaces between them toallow the escape of moisture issuing from the cloth under treatment. Acovering (7, of felt or other suitable material, is fastened on eachcylinder. The cylinders are driven from a shaft a, through gears e e aand both rotate in the same direction. Be-

low each cylinder is supported an arm j, which is hollow, so that steammay be admitted to itfor purposes of heating, and said iron isconcavo-convex in form, having a smooth concave face f, concentric withthe cylinder and adapted to co-act therewith in ironing the cloth; and asmooth convex under surface f one end of the iron is rounded, as at f sothat the cloth may pass readily over this end from the under to theupper side of the iron. The iron is supported in a hearing g, whichpermits it to rock and adjust itself to the cylinder and the cloth undertreatment, and said bearing is fastened on an arm g, pivoted at one endto the frame of the machine. Adjustment of the iron to suit the materialunder treatment may be effected through a worm 9 having a handle y asegment-gear g in mesh with said worm and carrying a gear 9 and asegment-gear g fast with the arm g and in mesh with said gear 9 It willbe seen that, by turning the handle 9 the iron may be lowered or raised,and 5 5 thereby adjusted with relation to the cylinder. An endless apron7t passes around rollers 71' h 71 in bearings fastened to the ends ofthe irons f, and engages the convex surfaces of said irons. Theniiddleroller 72. and 6c the roller h are supported above the irons, in closeproximity to the cylinders, so that, at these two points, the apronextends from the ends of the iron toward the cylinders, so as toproperly guide the cloth. This apron passes from the roller 71., whichis located at one side of the iron f, under the convex surface of saidiron, and thence over the roller 72 from whence it is carried under theconvex surface of the second iron f and over the roller 72. Said apronis carried from the roller 71, downward to and under a roller h,supported in bearings on the machine frame, and thence under atension-roller h and back to the roller 7K. The tension-roller 71, iscarried in bearin gs 7L6, each mounted on a vertical screw-shaft M,which is supported in fixed bearings on the frame. Said screw-shaftcarries a wheel 7L8, by which it may be turned and the tensionrolleradjusted to regulate the tension of the apron 7L according to theadjustment of the irons.

The operation is as follows: A piece of cloth to be ironed is firstintroduced between the apron and the under surface of the iron at theright-hand end of the machine, and the said apron, being constantlydriven, carries the cloth over the said under surface, at the same timepressing it against the same. The cloth is turned over the rounded endof the iron, as indicated by the arrow in Fig. 2, and then passes backbetween the concave surface of the iron and the cylinder, and thelatter,being constantly rotated, carries the cloth around with it. The underand upper ironing surfaces of the iron both act on one side of the clothas it passes around the'iron. After the cloth passes over the top of thecylinder, it is carried therefrom over the apronroller W, as indicatedby the arrow in Fig. 2, and thence passes between the apron and theunder convex surface of the second iron.

The cloth is carried around the end of the iron, and between the sameand the cylinder, as before, and thence passes up over the cylinder, andis carried off over the apron-roller 5 k The close proximity of therollers 7L2 and h to the cylinders prevents the cloth from returningunder the cylinders after passing over them. Guide-plates '5 are hingedin a position to hold the cloth upon the cylinders.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A mangle, comprising in its construction a rotary cylinder aroundwhich the cloth passes; an iron supported below the said cylinder, andhaving a concave ironing surface to co-act with the said cylinder, and acon- \Vitnesses:
